There was less sea ice in the Arctic on Friday than ever before on record, and the melting is continuing, the National Snow and Ice Data Center reported.

“Today is a historic day,” said Mark Serreze, a senior research scientist at the center. “This is the least sea ice we’ve ever seen in the satellite record and we have another month left to go in the melt season this year.”

Satellite measurements showed 2.02 million square miles of ice in the Arctic, falling below the Sept. 21, 2005, record minimum of 2.05 million square miles, the agency said.

The Internet is the new battleground against Islamist extremism because it provides ideology that could radicalize Westerners who might then initiate home-grown attacks, New York police commissioner Raymond Kelly said on Wednesday.

“The Internet is the new Afghanistan,” Kelly said, as he released a New York Police Department (NYPD) report on the home-grown threat of attacks by Islamist extremists. “It is the de facto training ground. It’s an area of concern.”

The U.S.’s top intelligence official has greatly expanded the range of federal and local authorities who can get access to information from the nation’s vast network of spy satellites in the U.S.

The decision, made three months ago by Director of National Intelligence Michael McConnell, places for the first time some of the U.S.’s most powerful intelligence-gathering tools at the disposal of domestic security officials.

The US government is on a ‘burning platform’ of unsustainable policies and practices with fiscal deficits, chronic healthcare underfunding, immigration and overseas military commitments threatening a crisis if action is not taken soon, the country’s top government inspector has warned.

Drawing parallels with the end of the Roman empire, Mr Walker warned there were “striking similarities” between America’s current situation and the factors that brought down Rome, including “declining moral values and political civility at home, an over-confident and over-extended military in foreign lands and fiscal irresponsibility by the central government”.

Global warming is forecast to set in with a vengeance after 2009, with at least half of the five following years expected to be hotter than 1998, the warmest year on record, scientists reported on Thursday.

Climate experts have long predicted a general warming trend over the 21st century spurred by the greenhouse effect, but this new study gets more specific about what is likely to happen in the decade that started in 2005.
